SPECIFICATION forming part of Letters Patent No. 355,915, dated January11, 1887.

Application filed September 22, 1886. Serial No. 214,225. (No model.)

To a/ZZ whom, t may concern.-

Be it known that l, JOSEPH I). BLACK, a

Y citizen of the United States, residing at Alton,

in the county of Madison and State of Illinois, have invented a new anduseful Improvement in C/ultivators, of which the following is aspeciiication. I

This invention relates to straddle-row Cultivators, and has the objectto improve the draft arrangement.'

The invention consists in certain improved construction, arrangement,and adaptation of parts, as hereinafter shown.

Referring to thedrawings, in which like letters refer to like parts inall the figures, Figure l is a perspective view of my improvedcoltivator, and Fig. 2 is a side elevation of same. Fig. 3 is a detailview enlarged, showing the parts in which my improvements are embodied.

My improvement may be applied to the ordinary cultivator having a frameconsisting of the axle B, wheels W, tongue T, seat S, and two gangs ofplows C, all of ordinary construe,- tion, as Shown.

A represents the drop-evener, consisting of two end frames and a centralframe pivotally connected to the tongue by the bolt b in Such a manneras to hold said drop-evener rigidly upright while permitting its endsto'vibrate and sway forward and back. Said end frames are provided witha top rail and a bottom rail, as will be understood by the drawings.

C represents the plows provided with the 4ordinary coupling, d, attachedto the bottom rail of said end frame, as shown in the drawings.

D represents the two-way or Y hitch, consisting of the singletree a,provided with the rod-link m, connected to the bottom rail of said endframe, and the chain n, connected to the top rail of said end frame bymeans of the bracket-hook e, as shown in Fig. 3. The said chain isadjustable upon said hook, by which it may be made shorter or longer andthe single-tree elevated, as shown Vby the dotted lines in Fig. 2. Thesaid rod-link is a stiff rod provided with an eye-ring at each end, asshown.

In operation the draft is applied to the single-tree in the usual mannerthrough the tug or trace h, and the Y-hitch and the plows are bothcarried forward and back with theswaying vof the said drop-evener. Thedraft is transmitted direct to the plows through the rod m and saidbottom rail, and the chain n transmits more or less draft to the saidtop rail, according to the adjustment of the chain in elevating theSingle-tree above the straightline draft. (Shown in Fig. 21) When theoperator is riding seated in theseat S the weight of the operator tendsto tip the machine backward and elevate the end of the tongue, toobviate which the chain n is shorttongue not liable to elevate or themachine to tip backward. Then when the operator is walking and theweight not upon the machine, the chain is adjusted to greater length,dropping the single-tree to its original position, when Said chain actsonly to prevent the single-tree from falling below theline of draft, andthe stiff rod-link m prevents the single-tree from falling back againstthe Wheel.

My invention is particularly adapted for the combined walking and ridingcultivator, in which the weight of the operator in his seat needscounteracting.

It will be observed that the relative position of the single-treeswiththe drop-evener and plows will remain the Same in all positionsofswaying of said drop-evener.

I am aware that drop-eveners have been `used before my invention, and Ido not broadly claim such; and I am aware that links, rods, and chainshave been used to connect the single-tree with the machine above to holdsaid single-tree from falling below the line of draft, and suoli I donot broadly claim.

. Having t-husset forth my invention,I claim--' JOSEPH P. BLACK.
